A system, device, and method for aggregating traffic in a network, such as for wireless backhaul traffic in a cellular communication system. UE device traffic is sent to and from an access bridge, which is one node in an access network formed into a ring topology, and from the access bridge to a core bridge in communication with a core network of the communication system. According to a preferred embodiment, the access bridge and the core bridge each have a LAG component configured according to IEEE 802.1D and IEEE 802.3-2005, and a ring component configured according to IEEE 802.1Q or 802.1AD. In operation, this LAG component load balances communication traffic coming into the bridge node onto one of two VLANs formed of portions of the access network ring. In the event of a fault condition affecting one of the two VLANs, the fault VLAN is removed from the aggregation scheme until the fault condition is alleviated.
A network node for use in an Ethernet ring network, the network node comprising:
A method of aggregating traffic to a core network via an access network comprising a plurality of network nodes, the method comprising:
A communication system comprising a plurality of access nodes configurable in a ring topology, wherein the plurality of access nodes comprises a first bridge node and at least a second bridge node, each bridge node comprising a ring component for establishing a first VLAN comprising a first subset of the plurality of access odes and a second VLAN comprising a second subset of the plurality of access nodes, and each bridge node further comprising a LAG component in communication with the ring component, the LAG component for communicating with an entity outside of the plurality of access nodes.
